Questions About Hip Scope Surgery

Hello,
i am a 22 year old female who recently fractured my right acetabular socket in three places. Luckily, the bone did not fragment and I did not have surgery. However, I have been having chronic pain and now the doctor says I may have to have scope surgery. I have an mri scheduled and the dr says that when they do the mri, they will inject the ink and also a numbing agent. The dr said that if the numbing agent takes the pain away while it is active, then I most likely do have something wrong and will need to have the surgery. I was wondering if anyone has had a similar experience like mine. I have been told that it is a very rare break to have, especially as a healthy, active 22 year old, although I have had a pin in my other hip as a result of an injury at 13. I am in the military and I hate to say this, but sometimes we do not always get the most thorough medical care, as the dr's are overworked and do not always have a lot of time evaluating the patient. This is also the third doctor I have seen about my hip throughout the healing process, so I am afraid that my diagnosis' are not consistent. Any information anyone might have about a similar injury would be most appreciated, thank-you!
